Nes Flashback: from Russia with falling blocks.

  I cannot express the admiration I have for this game and its impossible, probability.
      I remember hours of fun fitting block after block into place as fast as as possible in preparation for the inevitable fast paced level that would inevitably destroy me unmercifully. But no matter how many times it kicked my ass, I never got tired or bored with it.

There is no substitute for this game.  i tried tetris 2 and hate dr mario. <--- These games do not even begin to compare to Tetris.  Gameplay available here: http://www.nesfiles.com/NES/Play/Tetris
